Repository for the Elasticsearch Watcher extension library for NEST.
Watcher is a plugin for Elasticsearch that provides alerting and notifications based on changes in your data. This library extends NEST, allowing you to interface with the Watcher plugin.
PM> Install-Package Nest.Watcher -IncludePrerelease
| NEST.Watcher | NEST | Watcher |
|---|---|---|
| 1.0.0-beta1 | ≥ 1.5.1 | 1.0.0-Beta1 |
| 1.0.0-beta2 | ≥ 1.5.1 | 1.0.0 |
Once the package is installed, there is no need to include any additional namespaces as the extension methods are part of the Nest namespace and will immediately become available on any ElasticClient instance.
var client = new ElasticClient();
var response = client.PutWatch("my-watch", p => p
.Trigger(t => t
.Schedule(s => s
.Hourly(h => h
.Minute(0, 15)
)
)
)
.Input(i => i
.Search(srch => srch
.Request(r => r
.Body<object>(b => b
.MatchAll()
)
)
)
)
.Condition(c => c.Always())
.Actions(a => a
.Add("test_index", new IndexAction { Index = "my-index", DocType = "my-type" })
)Just like the core NEST client, an object initializer syntax is also available for all Watcher API methods:
var request = new PutWatchRequest(watchId)
{
Trigger = new TriggerContainer
{
Schedule = new ScheduleContainer(
new HourlySchedule
{
Minute = new int[] { 0, 15 }
}
)
},
Input = new SearchInput
{
Request = new SearchInputRequest
{
Body = new SearchRequest { Query = new QueryContainer(new MatchAllQuery()) }
}
},
Condition = new AlwaysCondition(),
Actions = new Dictionary<string, IAction>
{
{ "test_index", new IndexAction { Index = "my-index", DocType = "my-type" } }
}
};
var response = client.PutWatch(request);...and async support for all methods as well:
var response = client.PutWatchAsync(request);
var response = client.GetWatch("my-watch");var response = client.ExecuteWatch("my-watch", w => w
.TriggerEvent(t => t
.Schedule(schd => schd
.ScheduledTime(new DateTime(2015, 05, 05, 20, 58, 02))
.TriggeredTime(new DateTime(2015, 05, 05, 20, 58, 02))
)
)
.AlternativeInput(i => i
.Add("foo", "bar")
)
.IgnoreCondition()
.RecordExecution(true)
);See the tests for more examples. Also, refer to the official Watcher documentation for the full API.
